The Vixen Comet Book App - Free for Apple/Android Devices

The free Vixen Comet Book app, available at the App Store or from Google play, displays a star chart for your location and clearly marks where Comet ISON is located. Easy to use and quick to learn, the Comet Book is a nice tool to have at your fingertips whenever you want to check the position of Comet ISON, and it works great as a general real-time star map, too!

Highlights….

The star chart on the screen is synchronized with a real view of night sky for your current time and location.

Pressing the "Select Comet" icon lets you choose which comet you want to see on the chart. Comet ISON is on the list, but so are comets PANSTARRS and LEMMON.

Hit the play icon to see how Comet ISON moves across the sky over several weeks.

Change the date and time displayed by moving the sliders at the bottom of the chart.

Click the Cassiopeia icon to chose your choice of screen view. Choose the full screen view to see stars under the horizon.

Turn on Night Vision Mode (black background with red objects and markings) or control the brightness of your screen by accessing the “Setup” menu (wrench icon).

Check to make sure your location is correct by clicking the green GPS icon. You will be shown the latitude and longitude being used by the app.
